Answer:
To make a table u need to have coordinates, (x, y).
Solve for them using substitution:
y = x - 4 ↔ x = y + 4
y = (2x - 17)
PLUG IN TO y = (2x - 17).
y = (2(y+4) - 17)
Solve for y:
y = 2y + 8 - 17
y = 2y - 9
-1y = -9
y = 9
Solve for x:
x = (9) + 4
x = 13
Keep solving for x and y to have your coordinates for your table.
Answer:
Probability is 0
Step-by-step explanation:
The key information is that the data is normally distributed.
In a normal distribution, each individual value of hours has a probability equals to zero. It is a continuos distribution which is centered in the mean value, and where the expected value is the average.
As the distribution it is centered in the mean value, and it is symmetrical, then the probabilty of a bulb lasting more than the mean value is 0.5, and the probabilty of lasting less than avergare is 0.5 as well, but each individual valu is 0
